Cotton Bacterial Barriers (Part 2)
Cotton has long been used as a fabric of choice for wound dressings, gauze pads and other medical applications due to its high absorbency. Treated with chitosan, the fabric encourages healing of wounds. Another product that they have come up with is a cotton fabric that has been treated with negatively charged phosphoric acid that pulls positively charges proteases out of a wound. Protease is vital for healing, but too much can results in inflammation and can even prevent healing prolonging the renewal of skin cells to shield the underlying tissue. These breakthroughs in fabric design and treatment allows better products that resist or prevent infections such as in hospitals where beddings can become a propagation method for bacteria and other applications where cloth is used.
